Question

For a hypothesis test of H0: p = 0.35 against the alternative Ha: p > 0.35, the z test statistic is found to be 2.45. What can be said about this finding?

Answer 1

The z test statistic of 2.45 suggests evidence to reject the null hypothesis H0: p = 0.35 and support the alternative hypothesis Ha: p > 0.35.

Step-by-step explanation:

For a hypothesis test with the null hypothesis H0: p = 0.35 and the alternative hypothesis Ha: p > 0.35, a z test statistic of 2.45 was obtained. To interpret this finding, we compare the z test statistic to the critical value for the chosen significance level.

Given the information provided, we do not know the significance level or the sample size, which makes it difficult to determine the exact conclusion from this finding. However, based on the information given, we can say that the z test statistic falls in the rejection region, which suggests that there is evidence to reject the null hypothesis H0: p = 0.35 and support the alternative hypothesis Ha: p > 0.35.
